Zusammenfassung:	The invention discloses an embedded blade root, a manufacturing method, a blade, a power generation device and a bolt sleeve. The embedded blade root comprises a blade root body and a plurality of bolts. The blade root body comprises a blade root section extending in the axial direction of the blade root body, and the blade root section is annular. The multiple bolt sleeves are distributed in the circumferential direction of the blade root section, each bolt is inserted into the blade root section, and connecting holes extending in the axial direction are formed in the bolt sleeves. The embedded blade root is connected with the wind turbine generator through a plurality of bolt sleeves and connecting bolts which are axially arranged on the blade root section, and the maximum width size of the bolt sleeves in the radial direction of the blade root section is larger than the maximum width size of the bolt sleeves in the circumferential direction of the blade root section, so that the embedded blade root does no
